High Quality Content by WIKIPEDIA articles! Your Spaceflight Manual is a non-fiction book by David Ashford and Patrick Collins that investigates the possibility of a future space tourism industry. It was first published in 1990. The book contains analysis of the costs and benefits, the potential market and the safety factors of space tourism, and gives rough designs for the types of space vehicles and stations that would become necessary to support a full-fledged space tourism industry. This culminates with a description of a large space hotel (parts of which are spun to generate rotational artificial gravity) featuring attractions such as zero-gravity sports arenas and Earth-gazing observatories.
